Effects of N source concentration and NH4(+)/NO3(-) ratio on phenylethanoid glycoside pattern in tissue cultures of Plantago lanceolata L.: a metabolomics driven full-factorial experiment with LC-ESI-MS(3.).

Sándor Gonda et al.

Phytochemistry, 106, 44-54 (2014-08-02)

Tissue cultures of a medicinal plant, Plantago lanceolata L. were screened for phenylethanoid glycosides (PGs) and other natural products (NPs) with LC-ESI-MS(3). The effects of N source concentration and NH4(+)/NO3(-) ratio were evaluated in a full-factorial (FF) experiment. N concentrations

Simultaneous analysis of vitamins B in pharmaceuticals and dietary supplements by capillary electrophoresis hyphenated with triple quadrupole mass spectrometry.

K Maráková et al.

Die Pharmazie, 69(9), 663-668 (2014-10-03)

The advanced hyphenated method based on capillary electrophoresis (CE) on-line combined with electrospray ionization (ESI) and tandem mass spectrometry (MS/MS, here triple quadrupole, QqQ) was developed and applied in pharmaceutical analysis in this work. Under the optimized CE separation (background

Simultaneous analysis for water- and fat-soluble vitamins by a novel single chromatography technique unifying supercritical fluid chromatography and liquid chromatography.

Kaori Taguchi et al.

Journal of chromatography. A, 1362, 270-277 (2014-09-10)

Chromatography techniques usually use a single state in the mobile phase, such as liquid, gas, or supercritical fluid. Chromatographers manage one of these techniques for their purpose but are sometimes required to use multiple methods, or even worse, multiple techniques

Determination of four forms of vitamin B12 and other B vitamins in seawater by liquid chromatography/tandem mass spectrometry.

Katherine R Heal et al.

Rapid communications in mass spectrometry : RCM, 28(22), 2398-2404 (2014-10-11)

Vitamin B(12) is an essential nutrient for more than half of surveyed marine algae species, but methods for directly measuring this important cofactor in seawater are limited. Current mass spectrometry methods do not quantify all forms of B(12), potentially missing

Gene expression differences in infected and noninfected middle ear complementary DNA libraries.

Joseph E Kerschner et al.

Archives of otolaryngology--head & neck surgery, 135(1), 33-39 (2009-01-21)

To investigate genetic differences in middle ear mucosa (MEM) with nontypeable Haemophilus influenzae (NTHi) infection. Genetic upregulation and downregulation occurs in MEM during otitis media (OM) pathogenesis. A comprehensive assessment of these genetic differences using the techniques of complementary DNA

Protein enrichment of an Opuntia ficus-indica cladode hydrolysate by cultivation of Candida utilis and Kluyveromyces marxianus.

Gabriel B Akanni et al.

Journal of the science of food and agriculture, 95(5), 1094-1102 (2014-11-06)

The cladodes of Opuntia ficus-indica (prickly pear cactus) have a low protein content; for use as a balanced feed, supplementation with other protein sources is therefore desirable. We investigated protein enrichment by cultivation of the yeasts Candida utilis and Kluyveromyces

Reversed-phase high-performance liquid chromatography method with coulometric electrochemical and ultraviolet detection for the quantification of vitamins B1 (thiamine), B6 (pyridoxamine, pyridoxal and pyridoxine) and B12 in animal and plant foods

Lebiedzinska A, et al.

Journal of Chromatography A, 1173, 71-80 (2007)

A new approach for automated liquid-liquid extraction in a sequential injection manifold.

Irene Delgado-Blanca et al.

Analytical and bioanalytical chemistry, 407(2), 521-528 (2014-11-06)

A new approach for the implementation of liquid-liquid extraction in a sequential injection manifold is presented. The manifold consists of two syringe pumps and one multi-position valve. The use of a 30 % MeOH/H2O (v/v) solution as the carrier, with isobutanol

Extraction procedures for the liquid chromatographic determination of thiamin, riboflavin and vitamin B6 in foodstuffs

Ndaw.S, et al.

Food Chemistry, 71, 129-138 (2000)

Pyrroloquinoline quinone-secreting probiotic Escherichia coli Nissle 1917 ameliorates ethanol-induced oxidative damage and hyperlipidemia in rats.

Ashish K Singh et al.

Alcoholism, clinical and experimental research, 38(7), 2127-2137 (2014-06-17)

Chronic ethanol (EtOH) consumption is associated with oxidative tissue damage, decrease in antioxidant enzyme activities, and increase in hepatic and plasma lipids. This study investigates the effect of modified probiotic Escherichia coli Nissle 1917 (EcN) secreting pyrroloquinoline quinone (PQQ) against

Prion protein-coated magnetic beads: synthesis, characterization and development of a new ligands screening method.

Marcela Cristina de Moraes et al.

Journal of chromatography. A, 1379, 1-8 (2015-01-13)

Prion diseases are characterized by protein aggregation and neurodegeneration. Conversion of the native prion protein (PrP(C)) into the abnormal scrapie PrP isoform (PrP(Sc)), which undergoes aggregation and can eventually form amyloid fibrils, is a critical step leading to the characteristic

Capillary electromigration techniques as tools for assessing the status of vitamins A, C and E in patients with cystic fibrosis.

Ilona Olędzka et al.

Journal of pharmaceutical and biomedical analysis, 102, 45-53 (2014-09-23)

The purpose of this work is the evaluation of the nutritional status of patients with cystic fibrosis (CF), based on the level of vitamin C in urine and vitamins A and E in serum, using the fast, selective and fully

The Janus kinase 2 inhibitor fedratinib inhibits thiamine uptake: a putative mechanism for the onset of Wernicke's encephalopathy.

Qiang Zhang et al.

Drug metabolism and disposition: the biological fate of chemicals, 42(10), 1656-1662 (2014-07-27)

The clinical development of fedratinib, a Janus kinase (JAK2) inhibitor, was terminated after reports of Wernicke's encephalopathy in myelofibrosis patients. Since Wernicke's encephalopathy is induced by thiamine deficiency, investigations were conducted to probe possible mechanisms through which fedratinib may lead

High-performance liquid chromatography method for the simultaneous determination of thiamine hydrochloride, pyridoxine hydrochloride and cyanocobalamin in pharmaceutical formulations using coulometric electrochemical and ultraviolet detection
